If it is noticeable in 3 pictures then it is noticeable in real life. But that wrinkling could just be the drape after being in the box. Let it hang overnight.Your shoulders are each built differently and probably aren't exactly symettrical. To me, the right one looks filled in appropriately, perhaps because it is higher, but the left looks a wee tide wide. Do other jackets look the same? The sleevehead is just a little strong. It's not egregious in any way in my mind.

I have a similar problem. My choice not to wear several cuts of their suits is because too much chopping would need to be done to either the pants or jacket. so for you it depends on how much you're willing to do. At least have a tailor pin it and you can see how severe.

If you zoom in on the pictures on the SS site you'll see that some have a subtle pattern. I am wearing P3458 right now and it has a plaid design. It looks fairly dark in these pictures, but in real life and bright lights you can tell it is blue. I would personally choose a navy (P2778) as my workhorse.
